Trying very hard not to panic - CSA

Soon to be exH was supposed to make his first CSA payment last week. He defaulted. CSA has already chased him and not being able to contact him, contacted his HR department. They told the CSA that he no longer works there. Hence my utter panic. I finally get hold of him and he laughs, of course he works there, and indeed he is at his desk.

So I spoke to the CSA again, who will fax a request to the HR to reclarify if he works there or not. The CSA said that because they already specified who he was, by giving his NI number and other identifying information and were certain they could not have the wrong information.

Has anyone else had a similar experience?

I am fearful as the soon to be exH has a "gardening leave" clause in his employment contract.

Oh I am definately being screened, along with the CSA no doubt. But in the absense of any information from the CSA, I am speculating as to how the CSA can be told by HR he dosent work there, yet he is in the office, insisting he works there.
